Question about Pioneer DEH-1100 CD Player

Open Question

New head unit worked for a bit, stopped working

And now the old one won't work either

... except it's not the fuses.

We've checked the fuses with an ammeter. We've checked the fuse in the head unit and the one in the fuse board of the car. I assume there's no other one?

The new head unit won't work and neither will the old one, now (although it does occasionally light up for a brief moment and stop working. I have a Pioneer DEH-1100MP and am replacing a factory standard Rover 45 cassette player (which I think was re-installed recently - just bought the car).

Also checked the wires running to and from the unit, which are running at a current both ways of 12.6 or thereabouts. I'm tempted to think there's something wrong with the new head unit but can't figure out why the old one won't work (also just tried replacing fuse on fuse board)

The sellers of the CD player are willing to take it back, but if there's nothing wrong I will have to pay delivery charges to get back something that doesn't work. I'd like to avoid that if possible!

And we did swap the yellow and red wires as we should have done, and then tried the other way after it wouldn't turn on again.

Oh yes. Definately. You hook up red and yellow wires together on the positive side of battery. Black negative wire goes to negative on battery. That's all there is to it. Besides the speaker wire which you will have a diagram on the bottom of the cd player to tell you which wire is which

Is it older then a year? warranty or call18004211404. If your fuse is good check these. check you harness for a GOOD ground, check for power with a meter reader. For some reason on these units if your constant 12v and ignition 12v are both not hooked up it wont even do a thing. make sure both are connected. no loose connects?

Eject button won't work


What is the unit? There are often times in these new systems a belt or gear mechanism that moves the head base as well as other parts around. As units get older they need lubrication and the grease hardens to where they do not move as well. Belts also stretch and need to be replaced. When the head base mechanism is up or the mechanical alignment of the mechanism is NOT in stop mode or eject position the door is blocked from allowing it to open. The solution is to open the unit up and release the tape by a orderly means and then to work on it or have it worked on by someone who understands these units.

Can I replace the head unit in a 2004 saab 9-3 ? I've heard you can't because to car won't accept any other radios in it . I'm looking to replace it with a touch screen head unit .


Thanks for the help ...so your saying that if I for example buy a ...pioneer stereo that is the right size then it should have no problem hooking into the car with out any fancy wire work ....I'm for iliac with normal installation ( done it before ) but I'm just a little intimidated by some of the sites saying that you can't install a after market radio into a saab because it won't exempt it and all that stuff . But any right size stereo should work your telling me ?

Generally, with a gas dryer, there is an ignition device that heats to a specific temperature and this causes the gas to ignite. When this electric ignition fails to work, the gas will not ignite and there will be no heat. I had this happen and had to call a professional. It was a simple matter of installing a new ignition device and it worked perfectly for years. I hope this helps! If it is a new dryer, check to see if this part might be covered under warranty

take one of the front speakers out and pull out the head unit and unplug a set of audio wires(front right, front left ect.) and hook it up directly from the radio to the speaker there for bypassing all the cars wires. If it works then there's a problem with the car's wiring(maybe an inline amp). If it doesn't work, then try a known good speaker from somewhere else(home stereo speaker for example) and connect it to the radio, if the speaker works, your radio is fine and there may be a problem with the speakers. If it doesn't work then you have a problem with the head unit.

  • If there are no brake lights period the check the stop switch (brake light switch)
  • This is attached to the upper part of the brake pedal itself. Should be a little wire off of it. When that goes bad the brake lights will not work at all.
  • Please note that the fuse for "brakes" is ABS only and has no bearing on the brake lights themselves working.

Radio Works, but Screen is out, Fuse Ok


If everything else is still working and the Fuse is good it is Because the Internal Lighting on the Head Unit is Burnt out. The only way to Fix this is to get a New Head Unit.
